STOVEPIPE ATTACHMENT.

To all whom it may concern:

Be it known that I, JOSEPH H. ALLEN, a citizen of the United States,residing at Sedalia, in the county of Pettis and State of Missouri, haveinvented new and useful Improvements in Stovepipe Attachments, of whichthe following is a specification.

This invention relates to devices for retaining stove pipes in thimblesand for hold ing the pipe collars in proper position.

The principal object of the invention is to provide a simple andeilicient device which will be cheaply manufactured and sold and whichwill be conveniently applied so as to secure the stove pipe within thethimble and, at the same time, secure the collar against the wall.

Further objects of this invention will appear as the following specificdescription is read in connection with the accompanying drawing, whichforms a part of this application, and in which Figure 1 is a viewshowing the pipe and attaching device in elevation. Fig. 2 is asectional view taken through the pipe, the thimble, and the wall. Fig. 3is a perspective view of the attachment removed from the pipe andthimble,

Referring more particularly to the drawing, 1 represents a wall suitablyapertured to receive the flue thimble 2. This fine thimble isconstructed, as is usual, with an overhanging flange 3 to engage thewall,

which flange in this instance is cut away to receive the retainer awhich. is driven between the outer face of the thimble and the wall orthe flue aperture. The retainer is held secured in position by having aright angular head secured to the wall by fastening devices and itsopposite end bent over the inner edge of the flue thimble, as shown at6. The head is provided with a raised rib 7 which forms a groove for thepassage of the locking device, to be hereinafter described.

The pipe 8, when seated in the flue thimble, is provided with anaperture 9 adapted to receive the end of the locking device and thecollar 10 formed to fit close to the wall over the head 5 and has agroove 11 to receive the locking device. This looking device comprises asingle strand of wire Specification of Letters Patent.

having an elongated leg 12 adapted to enter the groove formed by the rib7 and enter the aperture 9 in the pipe, thus locking the pipe againstmovement in the thiinble 2. Intermediate the ends of the strand, thelocking device is bent at right angles and formed into a spring coil 13,the terminal of which is extended substantially parallel to the leg 12and ends in a down turned portion 1a, which overhangs the collar 10 andsecurely holds the same in position against the wall.

It will be noted that after the retainer has been secured to the walland to the thimble, all that is necessary is to place the pipe in thethimble and aline the aperture therein with the groove in the head ofthe retainer, slip the collar over the pipe, and insert the long end ofthe locking device into the groove and aperture. In so doing, the shortleg with its downturned portion will ride over the collar into theposition shown in Fig. 2 and thus hold itself against dis placement andagainst removal from the thimble and the collar in place against thewall.

What is claimed is 1. In combination, an ape-rt-ured wall, a thimbletherein, a retaining device secured to the wall and engaged with thethimble to prevent movement of said thimble, an aper tured pipe, acollar surrounding the pipe and engaged with the wall, and a lockingdevice passing through the retainer and through the pipe and havingmeans to hold the collar against the wall.

2. In combination, an apertured wall, a thimble secured therein, aretaining device connected to the thimble and to the wall and having anaperture therein, an apertured pipe seated in the thimble, a collarsurrounding the pipe and engaged with the wall, and a spring lockingdevice having a leg extending through the aperture in the retainer andpipe and provided with a leg to overhang the collar.

In testimony whereof I attiX my signature in presence of two witnesses.
